Window Screen Repair in LaSalle

LaSalle is a mid-sized borough on the island, and its housing stock is an unusually varied one. Three kinds of building meet here: post-war duplexes and small apartment blocks, 1950s and 1960s bungalows in the residential pockets, and apartment towers lined up along the river. Lachine, Verdun, Montréal-Ouest and Côte-Saint-Luc sit around it. That mix has a practical consequence: in LaSalle, whoever orders a screen repair is not always the person living behind it. It may be a duplex owner, an occupant on an upper floor or a bungalow owner. The work is the same, but the visit is organized differently: access to each dwelling, someone on site to open the door, the number of units to handle in the same building.

The other feature of the area is the sheer number of balconies and sliding patio doors. In a bungalow, a patio door is one opening among a dozen; in an apartment building or a tower it is often THE way outside, the one opened every day from May to September. So it wears out faster and differently: the mesh stretches in the middle from being pushed by hand, the flat rollers crush, the track fills with dust and grit. It is by far the most heavily used screen in this kind of housing, and the least well understood: when the door catches, people assume the door is finished when it is two rollers and a track. Redoing the hardware, then re-tensioning or replacing the mesh, gives back a door that rolls without touching the frame.

On a balcony patio door, everything happens from inside the unit. The screen panel lifts out of its track from the interior, is laid flat, rescreened, and put back: no outside access, no ladder, even on the tenth floor. That is worth knowing in an apartment building, because it is exactly what makes the repair possible without scaffolding or a lift. The faults are always the same three: mesh that has bellied out in the centre, worn rollers that let the panel jump the track, and the track itself, which has to be emptied and cleaned before anything goes back in. Taking the panel down is also the moment to change mesh type — a tighter weave on the river side, pet-resistant mesh where a cat climbs the panel.

In the 1950s and 1960s bungalow pockets you run into the classic narrow aluminum frame: a thin profile, a model no retailer carries any more, fitted to openings that match no size sold today. The frame is almost always salvageable — aluminum does not rot and can be straightened — and it is the mesh alone that has failed. Rescreening therefore keeps the original frame and avoids having a new one built to a dimension that cannot be found. In the post-war duplexes and small blocks the picture is less uniform: windows have been replaced in batches over the decades, so one building can carry sliders on rails on one floor and casements on another. Each dwelling is measured; nothing is inferred from the floor below.

LaSalle's constraint is multi-unit housing. In a building, the first thing to establish is who orders the work and who opens the door: the owner has the work done, but the occupants have to be there, dwelling by dwelling, since every screen comes off from the inside. A visit to a duplex or a small block is planned like a round of units, not like a house call. The second point is often misjudged: in a tower, height is not the obstacle, because nothing is done from the outside — but wind is, for the mesh. Standard mesh on a large panel high up works far harder than at ground level, and a stiffer mesh lasts longer there.

The river runs along the whole sector and supplies its share of insects: mosquitoes at dusk and finer ones — midges, no-see-ums — that cross a standard weave without slowing down. On a balcony where people sit in the evening, the tight weave is what actually changes the experience. Up high, add wind: mesh that is too soft flutters, stretches and eventually comes out of its spline groove; aluminum or a stiffer weave holds better. And in an apartment, the balcony screen is also the one the cat climbs — pet-resistant mesh prevents the claw hole that otherwise returns every spring. The working season runs April to October.
